文章大意】
科学家通过对12名志愿者实验观察，发现了为什么人在快乐和悲伤时，对时间长短的感觉相去甚远。
答案与解析】
38【答案】c
解析】课间十分钟玩得很开心，时间在不知不觉中就过去了。此处用can’t believe表示对这段时间飞快流逝的惊讶与感叹。
39【答案】c
解析】上文提到的是一种特定的心理场面描写，而不是人所经历的某一件具体的事情，故选c。scene情节，场面；experience经验，经历，阅历。
40【答案】a
解析】根据文中倒数第二段的解释可得知答案。drag拖长，此处指时间过的很慢。
41【答案】d
解析】thought over仔细考虑 ; make up 组成； suggest建议；表明； come up with提出。
科学家是以实验为基础进行研究而提出的一种原因。
42【答案】a
解析】联系下文的实验可知，当人的大脑集中于一个任务的多个面的时候，就变得比较活跃，反之，则变得不那么活跃。所以当大脑所注意的任务不同的时候，大脑的活动状态是不一样的。
43【答案】b
解析】联系上下文可知，人在比较厌烦或感到无事可做的时候，才觉的时间过得很慢。
44【答案】b
解析】时间过得很慢只是人的一种潜在的意识。
45【答案】d
解析】空格所缺的词作定语，应与前面的experiment构成动宾关系，结合下文进行的实验可知，只有d项符合。b项应改为carried out。
46【答案】c
解析】此处用while强调在实验过程中，被实验者与研究人员的任务对比关系。
47【答案】d
解析】根据后面的then; thirdly可得知答案。
48【答案】b
解析】根据后文49个空后面的解释可知，实验的目的是让大脑不停的专注于一个任务的多个方面。
49【答案】d
解析】此处指被研究人员的大脑思维比较活跃。
50【答案】d
解析】结合上文的实验可知，研究人员是让实验者的大脑专注于一个任务的多个方面。
51【答案】a
解析】be busy doing…忙于……为固定搭配；be likely to do…可能做……；be ready to do…准备做……；be sure of/about对……确信。
52【答案】d
解析】联系上下文可知，当大脑专注于一个任务的多个方面时，它的精力就会被分散，因而就转移了对时间的注意。spread 此处为分散。
53【答案】c
解析】此处是上述实验所得出的一个结论。
54【答案】c
